Plastic in medical technology: materials and requirements

Plastics in Medical Technology: Materials and Requirements

We work daily with plastics in various applications, but when it comes to medical technology the requirements are extra high. How can we choose the right material that meets both biocompatibility requirements and sterilization requirements?

One of the most important factors when it comes to plastics in medical technology is biocompatibility. That is, the material must be harmless to the patient and not cause any negative reactions. But what does biocompatibility really mean?

Biocompatibility

Biocompatibility is about how well a material interacts with the body. A biocompatible material should not cause inflammation, allergic reactions or damage tissues. There are different standards and tests to evaluate biocompatibility, such as ISO 10993. But how do we ensure that our plastics meet these requirements?

An important question is: How can we guarantee that our plastics are biocompatible? We must ensure that the material is clean and free from harmful substances. Additionally, we must test the material to ensure that it meets the requirements.

Sterilization

Sterilization is another important aspect when it comes to plastics in medical technology. The material must withstand sterilization without losing its properties. There are different methods for sterilization, such as autoclave, EtO (ethylene oxide) and gamma radiation. But which materials are suitable for these methods?

For example, PEEK is a material that is very suitable for implants, since it is biocompatible and can be sterilized with all these methods. But what is PEEK, and why is it so suitable for medical technology?

Common Materials

There are several common materials used in medical technology. PC (polycarbonate) is a material that is often used for housings and other components, since it is light, strong and can be sterilized with EtO. PTFE (polytetrafluoroethylene) is a material that is often used for catheters and other implants, since it is biocompatible and has low friction. But which material is suitable for joint implants?

PE-UHMW (polyethylene-ultra high molecular weight) is a material that is often used for joint implants, since it is very wear-resistant and can withstand the high loads found in joints. But how do we ensure that the material is strong and durable enough?

PEEK for implants
PC for housings and components
PTFE for catheters and implants
PE-UHMW for joint implants

Regulations

The regulations for plastics in medical technology are complex and include several different standards and directives. But how can we simplify this regulatory framework to better understand what requirements are placed on our materials?

An important question is: How can we ensure that our materials meet all relevant standards and directives? We must ensure that we have a good understanding of the regulatory framework and that we work with materials that are approved for medical technology.

We offer a range of materials that are suitable for medical technology, including PEEK, PC, PTFE and PE-UHMW. Our materials are all tested for biocompatibility and can be sterilized with different methods.

Summary

Plastics in medical technology require high demands on biocompatibility and sterilization. We must ensure that our materials are biocompatible, can be sterilized and meet all relevant standards and directives. But with the right material and a good understanding of the regulatory framework, we can create safe and effective medical technology products.
